quickly.
One sheet of paper will summarize the magnification parameters:
horizontal distance:
camera tilt:
L
7
optic-axis distance:
L- cos T
camera focal lengths: f
camera magnifications:
L-+ cos 7/f, and
the Hauser magnifications for each objective.
Another sheet will summarize the meteorological data, and will tabulate
air density p, and the fifth-root of the density, as functions of altitude; the
fifth-root data will also be plotted on graph paper against altitude.
Four additional sheets, one for each film, will tabulate for each picture measured:
the time and image diameter,
the corresponding object diameter, D
the parameter ¢ =D. 1-2/5, and also
op,1/5
Tables giving 1-2/5 as a function of t, will be provided to aid these last
two determinations, and the density chosen will correspond to analtitude
equal to one-fourth the diameter.
The computed parameter
will be plotted against log (time) to deter-.
mine the interval over which it is essentially constant.
Finally an average
figure will be determined for 1/5, over the indicated time interval and
over all four cameras; this value will be raised to the fifth power and multiplied by +x 1.272 x 1078 to obtain the total energy release in kilotons.
